Application filed August 21, 1890. Serial No. 382,603. (No model.)

To all whom it may concern: ably to provide bearings for the holders,

Be it known that I, CARL J. CARLSTROM, a which slide on the guidewaysduring the subject of the King of Sweden, residing at movements of thetool-holder, there being Jamestown, Chautauqua county, and State ofsufficient friction between the bearings and 5 New York, have inventedcertain new and the guideways to steady the holder in its usefulImprovements in Carving-Machines, of movement. These tool-holders 11 areadapted which the following is such a full, clear, and to bereciprocated on their bearings over a exact description as will enableany one skilled range of movement as great as may be necin the art towhich it appertains, to' make and essaryfor instance, a range equal tothe IO use the same, reference being had to the drawwidth of thework-table-the reciprocating 6o ings forming part of this specification.movement being imparted thereto by means My invention relates to amachine for carvof a pattern-belt hereinafter described.

This supporting-wheel 18 is peculiar arrangementsand combinations of preferably placed upon one side of the holder,

Figs. to by means of thepattern-belt hereinafter 5 and 6 are detached views of the patternto bedescribed. Thus each tool-holder 11 may belt and a portion of apattern-rack, thejoint be rocked or vibrated in its plane of recipro- 5use of which in the machine will outline the cation on an. axis normalto such plane. The figure shown in Fig. 7,,as will be fullyherebelt-pulley 20 of each ofthe tool-holders is i ft ib t preferablylocated to the side of the rocking Referring to the drawings, 10designates center thereof opposite that upon which the themachine-framing, which is made of asuitcarving-tool is located, so thatthe tension on 40 able form to contain the operative parts of the thespindledriving belt 22 may tend to coun- 0 machine. In the upper part ofthe framing terbalance the weight of the opposite end of are mounted aset of reciprocating and rockthe tool-carrier. The belts 22 afterleaving ing tool-holders 11, which carry the carvingthe drive-pulleys 23are crossed, one side pass tools 12, driven by spindles 13, which areproing over the pulley 20 and the other over the 5 vided with pulleys14. The tool-holders 11 pulley 21,and thence to the spindle-pulley 14,are each arranged, preferably, vertically and so that as thetool-holders are moved toward are provided with guideways 15, supportedthe rear of the machine and are brought more by the hangers 16, whichdepend from the directly over the drive-pulleys 23, which are upper partof the machine-framing 10. The located to the rear of the machine, thestretch 5o sides 17 of the tool-holders are formed suitof beltbetweenpulleys 23 and 20 will lengthen, Ioo

while that between pulleys 23 and 21 will shorten, thereby compensatingand keeping the tension on the belt uniform.

Each tool-hold er 11 is provided with an arm 26, extending from near therocking center thereof to slightly beyond the end of the toolholdercarrying the tool and forming a wide fork therewith, so as to embracewith ample clearance the work-table 61, the said arm 26 extending belowthe work-table and being provided with a guide 28, mounted adjustablythereon by means of set-screw 29, and which engages with the travelingpattern-belt 31. The guides 28 are form ed with a central opening 32 forreceiving the arm 26 of the toolholder and are provided with fiat sidebearings 33, which slide on the guide-bars 34,

fixed in the machine-framing in suitable po-' sitions. These guide-bars34 are preferably extensions of the tracks 19, upon which thesupporting-wheels 18 of the tool holders travel. The reciprocatory androcking movements of the tool-holders 11 are controlled by the patternsof the pattern-belt 31, which consist in the present construction, ofvsuitable sections 35, hinged together by links 35, and constituting anendless sectional belt, which is mounted upon the drums 37 and 38, thelatter of which effects the driving of the belt through means of shaft39, gears 40 41, shaft 42, pinion 43, fixed upon the latter, gear 44,pulley 45, the gear 44 and pulley 45 being keyed upon a sleeve 46,turning loosely on shaft 39. The pulley 45 receives its motion throughmeans of the band 47, which f passes over guide-pulleys 48 and 49 onshaft 50 and which receives its motion from the main shaft 24 throughmeans of pulley 51, shaft 52, band-wheel 53, belt 54, and pulley 55,fixed upon said main shaft. The patterns of the belt are composed ofsections or plates 56, which-are removably secured to the beltsections35 by means of fasteners or screws 57 and are provided with the patternribs or grooves 58,runninglongitudinallyof theplates and shaped after apredetermined design.

The pattern rib or groove 58 is engaged by the guide 28 of each of thetool-holders. In thecase where the part 58 is a rib or projection theend of the guide 28 engaging the same is notched or forked, as at 59, toreceive such rib or projection, which serves to move the guide 28 backand forth transversely of the pattern-belt, and thereby reciprocate thetool-holder and the tool carried thereby crosswise the Work 60, which isclamped upon the work-table 61. The rockingor vertical move-. ment ofthe tool-holder is imparted thereto by means of the pattern element 58of the belt in accordance with the elevations or depressions of thesame, as will be understood from the side view of the pattern-belt, asshown in Fig. 1. The pattern-belt therefore controls the extent ofmovement of the carving-tools made greater or less than that of theguide controlling said tool, since such a variation of position willvary the distance of the guide from the. center of the rocking motion ofthe tool-holder. The design of the pattern of each section thereof maybe alike, or the design formed by every two or more sections togethermay be alike. There may be as many sets of the pattern-sections runningside by side as there are tools to be controlled, in which case each setof pattern-sections would be engaged by. but one guide 28, which,instead of then being in a straight line longitudinal of thpattern-belt, would be disposed one in advance of the otherthat is tosay, to a person standing in -front of the machine, the carving-toolcontrolled by the guide which engages the set of pattern-sections 56near the front of the machine would be nearer to the observer than acarving-tool the guide of which engaged with pattern-sections nearer tothe rear of the machine.

By virtue of having the tool-holders so constructed that they may becontrolled by different sets of the pattern-sections the carving-toolscarried by the holders may be positioned so as not to be in the samevertical plane, and hence the cutting done byone tool is not worked.over by an adjacent tool when the reciprocating work-table 61 is madetotraverse a greater distance than the distance between the two adjacenttools. The upper portion of the pattern-belt is supported and maintainedin perfect horizontal position by means of the bed 112, as will beunderstood from Fig. 1.

The Work-table 61 is mounted horizontally upon the ways 62, and isreciprocated on its lengththat is, in the direction of the motion of thepattern-beltand is controlled in its movements by my novel form ofpatternrack 63. The work-table is provided with the fixed dogs 164 atone side thereof and with a clamp 165 at the opposite side thereof, bymeans of which dog and clamp the board 60, upon which the tools are tocarve, may be held firmly in position.

The pattern-rack 63 is formed after a predetermined design, the designdepending upon the design that'is to be carved. The pattern-rack 63 ismounted so that it maybe reciprocated lengthwise, and to that end it isprovided with a suitable guide-frame 64, which slides in the ways 65,secured to the machine-framing,and is detachably connected with thework-table 61 through means of the bracket 66 and the gravity latch orarm 67,

teeth and forms an endless or closed rack,

which runs straight in parts, then curved or serpentine, as may berequired by the'design The rack is fed or operated by'means of a gear71,n1ounted on an arbor 72, which is provided with a pinion 73, gearingwith a bevel-pinion 74, which is driven by the shaft 75.

- directly by the shaft 39 of the pattern-belt Y drum 38 through meansof the bevel-gears 76 back of the frame 87.

and 77, shaft 78, pinions 79 80, shaft 81, and cog-wheels 82 and 83, thelatter being keyed upon shaft 39, the peculiar arrangement of thegearing between the shafts 75 and 39 being rendered necessary on accountof the range of movement of the pattern-rack 63, which by sucharrangement is allowed to pass between the gears 79 S0 and 82 83. Theshaft 75, which feeds the pattern-rack, is formed with a joint 8l,whichin the present construction isin effectauniversaljoint.Theendoftheshaft75, upon which is fixed the pinion 76, is mounted in afixed bearing 85, while the other end thereof is'mounted in a bearing86, that is secured to a swinging frame 87. The frame 87 is mounted soas to swing in a plane parallel to the pattern-rack by means of abase-plate 88, formed with an annular groove 89, in which projects atongue 90, formed upon the The arbor 72 is mounted upon the end of theswinging frame 87, and the joint in the shaft 75 has the same center ofmotion as the swinging frame 87, so that the end frame 87 and the shaft75, mounted thereon, may be swung up or down while the shaft is running.The gear 71, which drives the pattern-rack, is held in engagement withthe teeth of the rack by means of a groove or slot 91, which runsparallel with the rack throughout and into which projects one end of thearbor 72, upon which the gear 71 is mounted. It will now be understoodthat the rotation of the gear 71 will feed the rack in one direction orthe other, according to the direction of rotation of the gear, whenrunning on the horizontal or curved poztions of the rack, but that itwill not effect any movement of the rack when running on the verticalportions thereof. In this way the back-and-forth movements,as well asthe periods of rest, of the work-table are under complete control of thepattern-rack.

In the foregoing description it will be seen that the design to becarved by my machine is controlled by the combined action of the twocomponent pattern mechanisms, one being the pattern-belt which controlsthe toolholders carrying the cutters and the other being thepattern-rack controlling the move- The shaft 75 is driven in-- ments ofthe reciprocating work-table. The joint effect of the simultaneousoperation of the two pattern mechanisms above alluded to will be readilyunderstood upon referring to Figs. 5, 6, and 7, wherein 31 is a form ofpattern-belt in which the sect-ions of the patternbelt are formed withpattern-grooves 58, which run either straight or obliquely across thesections and form acontinuous element running longitudinally of thebelt. Fig. 6 shows a portion of a pattern-rack which when used inconjunction with the pattern of the belt shown in Fig. 5 will cause theoutline shown in Fig. 7 to be carved. Supposing the feed-wheel 71 of.the pattern-rack to be at point a in Fig. 6 and moving in the directionof the adjacent arrow and that the patternbelt is passing under theguide 28 of one of the tool-holders at a point a in Fig. 5 and in thedirection of the arrow, by the time the feed-gear 71 has fed thepattern-rack from a to b, Fig. 6, the pattern-belt will have passedunder the guide 28 from a to b, Fig. 5, and the combined action of thesepattern devices will cause the carving-tool to cut the line from a, to bin Fig. 7. At this point there is a turn in the pattern-rack from b tob, and as this is almost a dead-point in the work the patttern of thebelt is so constructed from b to b that the carvingtool is raised out ofaction. As the patternrack is fed from b to c, Fig. 6, the patternbeltis moved from b to c, which resultant action causes the line to be cuton the work from b to c, Fig. 7. As the pattern-rack is fed from c to cthe belt moves from c to c,- and conjointly they produce the sharp turn0 in the work. As the pattern-rack is moved from c to d the pattern-beltis simultaneously moved from c to d, and the joint action produces onthe work the cut from c to d. The turn from dto d in the pattern-rack,combined with the stretch from d to d in the pattern-belt, producetogether another sharp angle in the work at d. The simultaneous movementof the pattern-rack from d to e and of the pattern-belt from d to Q willjointly result in the cutting of the line from d to e on the work. Theturn from c to e in the pattern-rack and thestret'ch from 6 to e in thetraveling belt conjointly produce the angular turn 6 in the work, andthen the movement of the rack from c tof and of the belt from c to fserve to cut the line from c tof on the work. (See Fig. 7.) In this wayby the simultaneous action of certain parts of the pattern-rack andpattern-belt, the relations of which are prearranged in accordance withthe design to be produced, the design is finally carved by the jointaction of the two component'patterns. The lines 000: (shown in Fig. 7)are carved simultaneously by different spindles, the work having to beput am enabled to carve a great variety of work. Moreover, differentpatterns may be readily substituted and the work rapidly turned out.

I desire to be understood as not limiting myself to the precise form ofconstructions of the pattern-belt and pattern-rack and the reciprocatingand rocking tool-holders herein shown or described or the particularform of the feeding mechanism for the pattern-rack, since thesefeatures, considered together or separately, are broadly new, as well asseveral other minor features which are particularly pointed out in theclaims.

It will be observed that the depth to which a carving-tool may cut willdepend upon theheight of the rib 58 of the pattern when a rib is used orthe depth of the pattern-groove when the groove is used. In the carvedfigure shown in Fig. 7 the points b d are repre: sented in thepattern-belt in Fig. 5 by the lengths of the pattern-groove 58 betweenthe 1 points I) b d d, the groove at this point berack, and thereforewhen the table is again to be connected to the p-atterrrrack another oneof the notches 70 of the bracket will be brought into use, and for thisreason there are to be a setof notches 70 in the bracket 66.
